COMPOSITE JOURNAL-BOX FOR CAR-TRUCKS.

Application filed May 3, 1916. Serial No. 95,041.

To all whom t may concern.'

Be it known that I, JUDsoN A. LAMON, citizen of the TJnited States, residing at Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Composite Journal-Boxes for Car-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to journal boxes for car trucks, and has for its object to provide an improvement in that class, or kind'which might well be called composite boxes to distinguish the same from the older, or integral casting kind or class of boxes. In the integral casting kind, the top andthe cellar are cast integral with each other, and if left unannealed are known as gray iron boxes and, if subsequently annealed, are known as malleable iron boxes.

The composite boxes are of two species. The older species-such as the box of the Schoen Patent, 482,200, of September 6, 1892, and of the Woods Patents, 904,665, of November 24, 1908, and 969,933, of September 13, 1910,-are usually composed of cast metal tops and sheet metal cellars, iirst separately and independently made, and then subsequently assembled and riveted together; and hence, by the removal of the rivets, the top and the cellar may be again separated and then be in their original forms. These may, therefore, be well called,sepa rable composite boxes.

The newer species of composite box is the invention of Ivar A. Randel; and, in its original form, was first disclosed and claimed in his Patent, 1,077 ,159, of October 28, 1913; and in its improved form, it is disclosed in his Patent, 1,090,085 of March 10, 1914:; and the process, by which he produces his box, in this improved form, is disclosed and claimed in his Patent 1,089,585, of March 10,1914.

If reference be made to these Randel patents, it will be seen that the cellar of sheet steelis first independently formed by the use of suitable dies, and then that 'the said cellar is placed in a. suitable mold and the top is cast fast to the cellar, and is itself formed in the casting operation. Because of this new process of manufacturethetop and the Specification of Letters Patent.

of re-use with any cellar.l Of course, the box may be sawed through, on horizontal planes, and this sawing could separate a sheet metal portion of the cellar from an upper portion of the box which would be composed chiefly of the cast metal of'the'top, but which would, of I necessity, still have integral therewith some portions of the sheet metal of the cellar.

From the'practical or commercial standpoint, therefore, 'the connection between the t'opandv the cellarv of the Randel box is an integral one; and the character of the connection is mechanically just as complete, for all practical or commercial purposes, as the connection between the metal of the top and the metal of the bodies or cellars of any of the old malleable iron integral casting boxes. Hence, the Randel box may well be characterized as an integral composite box. In all journal boxes for car trucks, the strains incidental to the service, come almost solely on the top, including the stop lugs, for the brass and the key, which stop lugs are usually formed integral with and constitute a part of the top; and moreover, these strains are chiefly taken at the central Zone of the top portion of the box.4 The cellar is practicallysimply la container for oil and waste, and must also be adapted to exclude sand, dust, and dirt,'and retain the oil without leakage.A lFor the reasons above stated, the top of the boxrn'iust have great strength to resist the strains of the service, and is always rigid and massive and relatively heavy as compared with the cellar which may be, and usually is, comparatively light.A The composite box is much lighter tion, which consists of the novel features hereinafter described, and defined in the claims.

Although my invention is capable of. use on both species of composite boxes, above identified and distinguished, it was specially designed to aiiord an improved composite box of the Randel or integral composite type g, andV hence, is so illustrated in theV drawings.

ln said drawings, like notations refer to like parts, throughout the several views; and, therein,

Figure 1 is a view in side elevation showing my improved box with some parts removed;

Fig. 2 is a view chiefly in plan, loolring down on the top of the box, but with a portion of the top broken away, and a portion of one side, and the rear end of the box, shown in horizontal section on the line z-2 of F ig. 1; Fig. 3 is a view of the box chiefly in front elevation, but with a portion thereof shown in vertical section, on the line rc3- x3 of Figs. 1 and'2; and I F ig. l is a fractional view, partly in front end elevation, but chiefly in vertical section on the line afl-m4 of Figs. 1 and 2.

The numeral 1 represents the pressed steel sheet metal cellar brought to the desired form by the use ofy suitable dies, and with the exceptions hereinafter noted is, or may be, of substantially the same form as that shown in the*l Randel patents above identified. rlhe most important exception or difference necessary here to note, is that my improved, cellar 1 is provided at its central zone with two outwardly extending corrugations a, and one inwardly extendingcorrugation b. The inwardly extendingI corrugation b extends for practically the full height of the side wall of the b0x,cand the pair of corrugations a are spaced apart from each other and coperate with the inward corrugation toaiord a seat for the jourl nal bolts (not shown). The pair of corrugations a are of flaring form, increasing upward, with their lower or smaller' ends merged into the main plane ofthe side wall of the cellar, and their upper or largerends open and terminating in the same horizontal plane as the other portions'of the sidewall of the cellar, as clearly shown in the drawing. v Y

rlhe cellar so; formedis placed in a suit` able mold, and the top 2 isformedand cast fast thereto by the process disclosed in the said Randel Patent, 1,089,585, steel being preferably used as the metal. The mold (not shown) is of such shape that portions of the molten metal will embracethe upper edges of the cellar, at all parts thereof, except at'rtheVA central zone, and `fuse:therewith, andc Shrink -zfast thereto,. r and theother portions of the molten metal will run through holes provided in the upper edges of the cellar, and cross-bond together the portions of the top which so embrace the edges of the cellar, all as disclosed in said Handel patents; and, the mold is further of such shape, that when the casting is completed, the top will have dependinfy stop lugs c, on the inside of the cellar, and a flat arch bar seat Z onvits top with projecting bolt lug flanges d overreaching the side walls of the said cellar, and `reinforcing ribs cV formed integral with the stop lugs c and the said projecting bolt lugs d of the arch bar seat.

Otherwise stated, in the casting operation,

the molten `metal will run into and fill the flaring corrugations c of the cellar, and will also surround the upper portionv of the straight corrugations and' will be fused fast to the walls of all three of these corrugations, and thereby the projecting por tion of the arch bar seat of the top, tor-wit, the bolt lug CZ', and the stop lugs c will be connected together. and reinforced by the said ribs c-all portions of this mass of metal being'integral. In this way, a top of great strength is secured, at the places where most needed, to wit, at the central zone, under the projecting portions of the arch bar seat, and directly opposite the stop lugs c. The cellar is of such shape as to affordl a flat tie bar seat f, .on its bottom, in the' same vertical plane as the arch bar. seat of its top, and, when the journal bolts (not shown) are applied to connect the boxto a truck of the arch bar type, they pass through the holes in the projecting portions or bolt lugs d of the arch bar seat and are themselves seated in the vertical corrugations b and between the flaring corrugations a of the cellar. Y

The mold is also of such shape that none of the molten metal. embraces the upper. edges of the cellar at, the central zone of the box, to-wit, none of those portionsy having the corrugations a and ZJ; andhence, when the box is completed, these corrugated portions of the upperedges of the cellar, simply abut against the side projecting ends or bolt lug portionsV CZ. of the` arch bar seat', asbest shown inFigs. .1, 3, and'lA of the drawing.

Fromthe foregoing, it must be obvious, that inA virtueV ofmy improvement, I am able to distribute the metal ofthe top lin a way most advantageous, for getting strength where' mostV needed, and at the same time, am able to get a sheet metal cellar which ,is integrally. connected to the top, and there-k fore, free from any joints which could open to admit sand, dust,vor dirt, or permit the escape-of oil under the vibrations incidental to the service.

If my invention, herein disclosed and claimed, waste beapplied to a` separable compesite1 box, thecellar andthe top would, 130

of course, be first separately made, and then subsequently assembled and riveted or otherwise secured together, and the cellar would have the same corrugations a and Z) as here shown, and the top would be of the same general shape, and provided with the stop lugs c, bolt lugs (Z, and the reinforcing ribs e formed integral with each other; and, when assembled, these parts of the top and the cellar would occupj7 the same relation to each other as in the box illustrated.

My improved box, when made by the Handel process, does not cost any more than the original Randel box. Of course, it must be understood that proportions and weights of the different parts, especially of the top, will vary for different sizes ofboxes, as required for cars of different capacities.

lt should also be understood that the mol d may be of such shape that the molten metal would embrace the whole of the upper edges of the cellar and be cast fast thereto, as in the Randel boxes, so that the completed box would have continuous flanges embracing the upper edges of the cellar. The continuity of the outer Hanges, however, is not essential. The central portions may be omitted so as to afford gaps in the outer flanges in that part of the box directly under the projecting ends or bolt lug portions d of the arch bar seat d, as illustrated in the drawings; and, the box has been so illustrated to show that this can be done, without materiallyweakening the box, or producing any open joints between the top and the cellar.

What I claim is:

A journal box comprising an independently formed metallic cellar and a top of cast metal cast fast to said cellar, the sides of said cellar having pairs of outstanding laterally spaced corrugations that extend from the extreme upper edges of said sides and taper downwardly and blend into the sides of said cellar7 and said cast top having integral stop lugs cast against the inner surfaces of the sides of said cellar, and in turn, having tapered reinforcing ribs cast into and fitting said tapered corrugations, and the said top further having overhanging bolt lug anges, the under surfaces of which aline with the upper edges of said corrugations, leaving the same exposed at the exterior of the cellar.

In testimony whereof I affix my signature in presence of two witnesses.
